Application filed November 21, 1913. Serial No. 802,267.

Patented Sept. 1, 1914.

To all whom it may concern:

Be it known that I, ERNEST S. KNEELAND, a citizen of the United States, residing at Malden, in the county of Middlesex and Stateof Massachusetts, have invented a new and useful Automatic Weighing Device, of which the followingis a specification.

The device forming the subject matter of this application is adapted to be employed for automatically weighing quantities of material which will flow readily.

The invention aims to provide novel means for controlling the closures of a receptacle in which the material is received, novel means being provided for directing the material first into one compartment of the receptacle and then into another compartment thereof.

It is within the-scope of the invention to improve generally and to enhance the util- "ity of devices of that type to which the present invention appertains.

, With the'abo've and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within 1 the scope of what is claimed without degers 10. Projecting from the collar 8 parting from the spirit of the invention.

In the drawing :Figure 1 shows the invention in side elevation; Fig. 2 is a section on the line 22 of Fig. 1; Fig. 3 is a transverse section; Fig. 4 is a detailed perspective of the latch.

In carrying out the invention there is provided a support '1 and as a preliminary statementvit may be set forth that the support may be of any desired form and may be positioned as the exigencies of the pro posed use of the structure may demand. In:

the present instance, the support 1 is shown as comprising a foot plate 2 supporting a standard 3. Surrounding the standard 3 and vertically adjustable thereon is a collar 4 held in place by a set screw 5, there being an arm 6 projecting from the collar and the arm terminating ina hoop 7. A collar 8 surrounds the standard '3 above the collar 4 and is fixed to the standard, the collar 8 being provided with a rearwardly extended arm 9 which is bifurcated to form guide fin- -in any other suitable manner.

alinementwith the arm 9 is an arm 11 termmatlng ln an upright head 12. Arms 14 pro ect from the collar 8 at an angle to the arms 11 and 9 and extend upwardly, the arms terminating in upright extensions 15.

Vertically adjustable upon the standard 3 above the collar 8 is a collar 16 held in place by a set screw 17, the collar 16 including a forwardly projectingarm 18 terminating in a supporting plate 19 as shown best in Fig. 2, the arm 18 and the plate 19 being provided with a band 20 or the like.

The invention includes a casing 21, the lower end of which is formed into an outlet funnel 22 fitting into the hoop 7. The head 12 of the arm 11 is secured to the casing 21. Located above the casing 21 isa hopper 23 including a laterally extended, inclined neck 24. The neck 24 is embraced by the band 20 and terminates in a spout 25 discharging into the top of the casing 21. Guides 26 are mounted on the hopper 23 and mounted for reciprocation in the guides 26 is a gate 27 which controls the neck 24 of the hopper,

the gate beingactuated by means of the link i 28 operated through the medium of a lever 29 which is fulcrumed on the hopper 23.

vthe arm 14 so that the scale beam is fulcrumed intermediate its ends. Slidable upon one side portion of the scale beam 30 is a tare weight 32 held in place by a set screw 33 or The intermediate portion of the scale beam 30 is provided with a lug 34 to which a common weight supporting hanger 35 is pivoted.

Located within the casing 21 beneath the funnel 25 and between theside portions of the scale beam 30 is a receptacle 36 which is pivotally supported upon the scale beam as shown at 37. The receptacle 36 is divided into two compartments by an upright partition 38.

Pivotally supported in the receptacle 36 and located above the upper edge of the partition 38 is a movable bafiie 39 having an arm 40. The arm 40 is adaptedto be engaged by stops 41 on the receptacle 36. A lever 42 is fulcrumedintermediate its ends upon the receptacle 36, the fulcrum of the lever being indicated at 43. The upper end of the lever 42 is loosely connected with the arm 40 by meansof a pin or slotunion and the like.

Pivotally supported at 44 upon the re- 5 ceptacle 36 is a movable member or segment 44 provided in its upper edge with a notch 45 defining projections 46. The lower end of the lever 42 lies between the projections 46. Pivoted at 47 to the receptacle 36 is a latch 48 provided with a laterally projecting finger 49 received in aslot 50 formed in the segment 44 and adapted to cocperate with opposite edges of a tooth 51 which projects into the slot 50 from the body portion of the segment. Extended from the latch 48 in an opposite direction to the finger 49 1s a fingerpiece 52 which projects outwardly through the casing 21. Downward swinging movement of the free end of the latch 48 is limited by the engagement between the finger piece 52 and the base or bottom of-a slot 52 in the casing 21, in which notch or slot the finger-piece 52 lies. I

Closures 53 are pivoted as indicated at 54 I to the receptacle 36 and control the egress of the weighed material from the compartments which are defined by the partition 38. Links 55 are pivoted to the closures 53 and are pivoted at their upper ends to the segment 44.

Let it be supposed that the gate 27 in the neck 24 of the hopper 23 is closed, that the movable baflie 39 is in the inclined position shown in Fig. 2 and that the lower end of the lever 42 is adjacent one of the projections 46 of the segment 44. Suppose that the finger 4901? the latch 48 is engaged withone side of the tooth 51 and that one of the closures 53 is in a position to cut off the outlet at one side of. the receptacle 36all of which details are clearly shown in Fig. 2.

Then the operation of the structure is as follows :W'hen the gate 27 is raised through the medium of the link 28 and the lever 29, the material in the hopper 23 will flow through the neck 24 and be delivered by the spout 25 against the inclined, movable bafiie 39. The baffle 39 will direct the flowing material into one of the compartments in the receptacle 36, say the right hand receptacle in Fig. 2, until sufficient material hasaccumulated in this compartment to overcome the weight carried by the hanger 35. Then, the scale beam 30 will tilt upon its fulcrums 31- 15 and the receptacle 36 will move downwardly. When the receptacle 36 moves downwardly, the finger 49 on the latch 48 will be disengaged from the tooth 51 of the segment 44. The segment 44 will be free to tilt on its pivotal support 44 and the weight of the material, resting upon the right hand closure 53 will, through the medium of the right hand link 55 effect a swinging of the segment 44 to the right.

"By this operation, the left hand closure 53 will be moved to a closed position and the finger 49 on the latch 48 will interlock with the left hand side of the tooth 51. When the segment 44 is swung in the manner hereinbefore described, the left hand projection 46 on the segment will strike the lower end of the lever 42 and tilt the lever, motion being imparted to the baffle 39 through the medium of the arm 40, the bafile being swung over so as to direct the material flowing from 76 the spout 25 into the left hand compartment of the receptacle 36.

From the foregoing it will be seen that successive charges of weighed material will be delivered automatically from the recep- 0 tacle 36 into the discharge funnel 22.

It will be understood that should it be desired to dump either of the compartments of the receptacle 36 at any time manually, the latch 48 may be manipulated through the 05 medium of the finger piece '52 to effect this result.

Having thus described the invention, what is claimed is 1. In a device of the class described, 4!) weighing means; a receptacle supported thereby and provided with compartments;
